Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"One of the nice things about Firepower is that you can set it to discover the environment. If that is happening, then Firepower is learning about every device, software operating system, and application running inside or across your environment. Then, you can leverage the discovery intelligence to get Firepower to select the most appropriate intrusion prevention rules to use for your environment rather than picking one of the base policies that might have 50,000 IPS rules in it, which can put a lot of overhead on your firewall. If you choose the recommendations, as long as you update them regularly, you might be able to get your rule set down to only 1,000 or 1,500, which is a significant reduction in a base rule set. This means that the firewall will give you better performance because there are less rules being checked unnecessarily. That is really useful.""Feature-wise, we mostly use IPS because it is a security requirement to protect against attacks from outside and inside. This is where IPS helps us out a bunch.""Its Snort 3 IPS has better flexibility as far as being able to write rules. This gives me better granularity.""It is one of the fastest solutions, if not the fastest, in the security technology space. This gives us peace of mind knowing that as soon as a new attack comes online that we will be protected in short order. From that perspective, no one really comes close now to Firepower, which is hugely valuable to us from an upcoming new attack prevention perspective.""The customer service/technical support is very good with this solution.""We get the Security Intelligence Feeds refreshed every hour from Talos, which from my understanding is that they're the largest intelligence Security Intelligence Group outside of the government.""The most valuable feature that Cisco Firepower NGFW provides for us is the Intrusion policy.""It's got the capabilities of amassing a lot of throughput with remote access and VPNs."

"The most valuable features in OPNsense are reporting and visibility.""We have found pretty much all the features of the solution to be valuable.""The solution is good for a basic firewall for a small business or for home use.""I have found the solution has some great features overall, such as guest access capabilities, dashboards, and ease of use. There is plenty of documentation and support and it has the plugins that I needed.""The graphic user interface is very good and it is user-friendly which makes the product easy-to-use.""The VPN server feature is the most valuable. It is integrated with Radius and AAA for doing accounting and authentication. Insight view is also an important feature for me at this time. It allows me to assess our network traffic. I also like the firewall feature. The BSD kernel has a packet filter. It is one of the most solid frameworks for firewalls. Its user interface is one of the best interfaces I have used.""The most valuable features are reporting, the Sensei plugin, and firewall capabilities.""OPNsense is easy to scale when running on the hardware."

"It's a very simple to use product.""Sangfor has the best capabilities for securing connections, securing web browsers, securing servers, and general threat protection.""While the features are not dissimilar to other brands, configuration is much more simple, which works out great for Indonesian people.""We've found the technical support to be helpful.""In terms of the most valuable features, the IPS report is quick and updated. Performance is also valuable.""In four steps one can configure the entire firewall."

Cons
"The initial setup can be a bit complex for those unfamiliar with the solution.""FirePOWER does a good job when it comes to providing us with visibility into threats, but I would like to see a more proactive stance to it.""I believe that the current feature set of the device is very good and the only thing that Cisco should work on is improving the user experience with the device.""Deploying configurations takes longer than it should.""The solution could offer better control that would allow the ability to restrictions certain features from a website.""The central management tool is not comfortable to use. You need to have a specific skill set. This is an important improvement for management because I would like to log into Firepower, see the dashboard, and generate a real-time report, then I question my team.""They need a VTI. I know it's going to be available in the next software version, which is the 6.7 version. However, the problem with that is that the 6.7 is going to deprecate all the older IKEv1 deployment tunnels. Therefore, the problem is that we have a lot of customers which are using older encryptions. If I do that, update it, it's not going to work for me.""Report generation is an area that should be improved."

More Cisco Firepower NGFW Firewall Cons »

"There should be more technical documentation.""I would like to see better SD-WAN performance.""The interface isn't so friendly user. But we have some technicians here who are quite confident with this tool. OPNSense could maybe add sets of rules so it's simpler to manage different groups with particular needs.""The logging could improve in OPNsense.""While they do have paid options that actually gives better features, for most of the clients, if they tend to take a paid option will instead opt for Fortinet.""The only thing that I would like to see improved is the Insight or the NetFlow analysis part. It would be good to have the possibility to dig down on the Insight platform. Right now, we can easily do only a few analyses. If this page becomes more powerful, it surely will be a well-adopted platform.""The solution could be more secure.""The solution would not be suitable for anything large-scale."

More OPNsense Cons »

"I believe that IAM and NGFW need to merge into a single box, instead of there being two separate box solutions.""The solution has too many bugs and these slow down the implementation.""They need to increase the number of ports in the firewall.""The web interface needs to be improved, making it more user-friendly.""Occasional issues with breaches which are dealt with expediently."

Pricing and Cost Advice
"When we purchased the firewall, we had to take the security license for IPS, malware protection, and VPN. If we are using high availability, we have to take a license for that. We also have to pay for hardware support and technical support. Its licensing is on a yearly basis.""This product is expensive.""It definitely competes with the other vendors in the market.""This solution is expensive and other solutions, such as FortiGate, are cheaper.""We normally license on a yearly basis. The hardware procurement cost should be considered. If you're virtual maybe that cost is eradicated and just the licensing cost is applied. If you have hardware the cost must be covered by you. All the shipping charges will be paid by you also. I don't thing there are any other hidden charges though.""The solution was chosen because of its price compared to other similar solutions.""This product requires licenses for advanced features including Snort, IPS, and malware detection.""The price for Firepower is more expensive than FortiGate. The licensing is very complex. We usually ask for help from Solutel because of its complexity. I have a Cisco account where I can download the VPN client, then connect. Instead, I create an issue with Solutel, then Solutel solves the case."

More Cisco Firepower NGFW Firewall Pricing and Cost Advice »

"The solution is not expensive.""As an appliance, it's in the medium price range.""OPNsense is an open-source solution and it is free to use.""OPNsense is a well known open-source tool.""OPNsense is open source software so at this time it is free for us to use.""It is not an expensive product. Basically, I deployed it because it was the fastest solution to satisfy our needs in open source."
